Abstract
The aim of this paper is to evaluate the impact on human health and on the
ecosystem caused by electricity produced by photovoltaic systems. The analysis
was carried out with the life cycle assessment methodology (LCA) and the eco
indicators method.
It includes a study of raw materials and energy consumption and their
polluting emissions in air, water and soil during the production phase in Europe
and transport, use and disposal in the city of Rome of the crystalline silicon and
all other materials and components used to produce 1 kWh of electricity. The
kWh is the functional unit of the LCA analysis.
The study considers the relationship between the energy consumption needed
to build a PV system and the energy produced by the same system over 25 years.
The study also considers the relationship between global and local environmental
impact caused by the manufacturing and disposal of the PV system and the
avoided environmental impact due to the energy produced by renewable sources.
Finally, the analysis compares global and local emissions of CO2 caused by the
PV system’s manufacturing and disposal and the avoided emissions of CO2 using
electricity from renewable sources. The study describes the possible solutions to
reduce environmental impact through innovation.
Keywords: PV system, LCA, Mayor’s Pact, saving CO2.
1 Introduction
The IV Report on Climate Change, referenced by the European Union in its
climate policies points out that within the first half of the century global
emissions should be reduced by at least one half compared to 1990.
